This keystone 2 in one black light and uv flashlight is amazing. Its exactly what my family and I needed and have been looking for. With my husbands and my job we move around and rent a lot. And renting with carpet it iffy. I feel so much more secure now that we have a high quality black light to see any and all stains to report and clean. This flashlight is very bright and reliable. It is made out of very sturdy metal to be used over and over lasting a lifetime. I also love how this flashlight is compact and easy to stow away for any move or storage. Overall great buy and I highly recommend.
